WIPER IVIECHANISIIVI FOR LABELING-MACS.

Specification of Letters Patent.

Patented April 1a, 1909.

Application filed June 18, 1906. Serial No. 322,196.

cation, reference being made therein to thev accompanying drawings.

The object of my present invention is to provide a practical and eflicient wiper mechanism for use in labeling machines, more es pecially designed for dual labeling, for the application of neck labels simultaneously :1 with the body labels.

Another object is to provide a wiper means for labeling machines, adapted for laying labels upon varying or curved surfaces, and operative for pressing the ends of a label beneath or around the under side of the bottle, or bottle-neck, by an undertucking movement in addition to the regular wiping movement, as more fully hereinafter explained.

Other objects and novel features of my invent-ion are set forth in detail in the following description, and the particular subject matter claimed defined in the summary.

In the drawings, Figure 1 represents a front view of wiper mechanism embodying my invention, one of the wiper heads being shown in section. Fig. 2 represents a trans verse verticalsection at line X on Fig. 5, showing portions of mechanism that are in rear of those exhibited in- Fig. 1. Fig. '3 is a diagrammatic view of one of the fingerplates or wiper-face members'and adjacent parts. Fig. 4 shows the back and side form of another one of the fingers or wiper-face members. Fig. 5 represents a side view of wiper mechanism with the wipers arranged for dual labeling, also indicating the relation thereto of the label-holder and picker devices. Fig. 6 represents the face of one of the undertucking wipers. Fig. 7 is a front view of my wiper mechanism as arranged with the wipers working at different levels for underlapping the ends of labels that extend more than the circumference of the bottle-neck or article to which the labels are affixed. Fig. 8 is a front view illustrating the operation in which the wiper has a degree of undertucking movement that carries the face of the wiping member laterally beyond the central plane of the bottle. F1gs.9,

the wiper-head is arranged to slide instead of swing upon a pivot axis.

' The improved mechanism illustrated is more especially desi ned for use in connection. with pickers, label-delivering devices and operating mechanisms similar in general character to that described in my prior application for patent, Serial No. 197,485, but the invention may be employed in labeling machines of other construction; and I do not, therefore, confine my present invention to a particular form of machine upon which to apply the improvements.

Referring to the drawings, the part indicated by the letter A. represents a portion of a suitable main ;frame, and D a reciprocating slide that is; moved u and down upon the guide G (by any suita le means) carrying the wiper-arms 0 ast the object to be labeled. In practice the wiper-arms have an upward and downward movement and a lateral or swinging action on the centers 2, so that the opposite wipers are closed to ether when they move downward ast the ottle B, which in supported in well nown manner by the stationary bottle-rest F, and are then opened or swung apart so as to clear the bottle when theymove upward; such movements being imparted to the wiper-arms by means of guides 4 and rollers 3 heretofore employed; or by any suitable means for effecting similar movement.

I indicates niyundertucking wi er which is supported in connection with t e wiperarm, preferably by a supplemental bracket or hanger C formed upon or attached to the wiper-arm O at or near the outer end thereof and adapted for wiping on neck labels, and H indicates an ordinary flexible-pad wiper fixed upon the wiper-arm at position for wiping onthe body labels.

L and L indicate the label supply packs sustained by any suitable label-holder; and Z and 1 indicate the labels as severally delivered by the pasting pickers P (indicated by dotted lines, on Fig. 5.)

In accordance with my invention, as shown in Figs. 1 to 8, the wipers I each comprise a gang or series of pivoted inwardly curved fingers or members 5 forming the working face of the wiper and supported on a pivoting axis or pin 6 mounted in a swinging head-piece 10 carried upon the 5 is best provided with a stud 14 for con wiper-arm, or its supplemental bracket C by a pivoting stud, shaft or axle 12 fixed therein, upon which the wiper-head 10 is supported to swing, preferably in pendulous manner back and forth, in lateral relation to the position of the bottle rest. The wiperhead is provided with seat lugs 7 and 8, and each individual wiper-finger is provided with an expanding tensioned spring 13 suitably arranged between an ofi set portion of the finger and one of said seat lugs, for normally projecting the wiping face. The fingeriece the end-of the spring in connection therewith The wiping-face members or fingers 5 may be made of plate brass or other suitable material that can be assembled to work in gang. The alternate members are preferably modifled in form, some being as shown in Fig. 3 and the others as shown in Fig. 4, so that their springs 13 are respectively disposed alternately at offset positions, as for instance in upright and horizontal positions, to bear I against the seat members 7 and 8 respectively thus affording ample room for each spring to work without interference.

Each member is provided with a projection, lug, or arm 15 that contacts with a stop or lug 9 for limiting the forward movement of the member by its spring, and bringing all of the members to a normal alinement at the face of the wiper. The springs afford a yielding pressure independent for each individual member or finger in the gang or series; thus producing a wiper-face composed of independently yieldable parts or members.

The finger members 5 are preferably arranged on their pivot-pin 6 with thin washers 16 between the adjacent members, althou h such washers may not in all instances e em loyed.

ombined with each of the laterally swinging or movable wiper-heads I provide means for independently moving the same in relation to the wiper-carrying arms. Such means in the present instance consists of a lever 20 fulcrumed at 21 u on the bracket C The upper end of said ever bears against a suita e boss or surface 17 of the wiper-head 10, while its lower end is provided with astud and roller 22 that moves into contact with a cam or pattern-surfaced member 23, supported on the frame A, for actuating the lever 20 when the wiper-arms move downward. A contractile spring 25 connects the lower part of.

each wiper-head with a projection 26 upon the lever 20. Said spring serves to swing the wiper-head outward in relation to the support bracket, and also to keep the upper end of the lever normally in contact with the boss or surface of the wiper-head.

The oppositely disposed wipers and wiperoperating devices are of similar constructlon, but made right and left in pairs. The description of. one of the pair will therefore apply to both; similar reference characters designate corresponding parts in the right and left positions.

The outward movement of the Wiper-head is arrested and limited by a suitable backstop device or lug 19 fixed on the support bracket C The wiper-head 10 is confined on its pivot 12 by a cotter-pin or similar fastening 11, which permits of the wiperhead being readily taken off the machine and washed out in case the members become clo ged with glue.

he drawing, Figs. .1 and 2, illustrates the position of the mechanism as in action at an intermediate stage of the wiping-on movement the wipers having commenced but not completed their action. In the o eration, the labels having been primarily g ued and delivered in well known manner above the bottle and there centrally clamped by a suitable grip device 27, the wipers are brought together above the label and then moved downward. The set of wipers H lays the body-label and the set of wipers I lays the neck-label simultaneously. At the first part of the movement the under side of the wiper-face members 5 press down the label L upon the upper curvature of the bottle; the lever 20 being meanwhile free from the cams 23 and the wipers are yieldingly influenced only by the springs 25; themembers 5 being pressed by the spring 13 so that their ends 15 are against the limiting stops 9.

At about the time the ends of the wiping members reach the sides or median curvature on the bottle, the lower ends of the levers 20, or their rolls 22, strike the cams 23 and the further downward movement causes the levers to swing and press the wiper-heads 10 toward each other, carrying the ends of the inwardly curved fin ers or members 5 beneath the neck of the ottle with a tuckunder movement that wraps the ends t (see Fig. 1) of the label about the under curvature, and presses them against the surface with a yielding pressure due to the tension. of the springs 13. The separate wiping-members 5 permit conformation of the wiper-face to the longitudinal curvature or irregularities of surface, so that alabel can be properly wiped on when laid more or less upon the arched shoulder of the bottle. When the rollers 22 have passed the cams 23 the levers 20 and wiper-heads 10 are relieved and can assume normal positions, and the rollers 22 can pass up at the inner side of the cams without effecting any operation of the mechanisms.

When the Wipers have performed their wiping-0n action, an opening operation of the wlper-arms C swings back the supportbrackets, together with the wiper-heads pivoted thereon, to the positions approximately sired to aflix labels which are of greater.

length than the circumference of the neck and are required to be lapped at their ends, the wipers I at the right and left hand ositions are arranged at different levels, as illustrated in Fig. 7 the lead 29 being about one inch, more or less, in a full sized machine. The same amount of lead is of course assumed by the levers 20 and their rolls 22 in approaching the cams 23. This difference in levels enables one wiper to act in advance of the other and to complete the wiping-on of one end of the label, and to get out of the way by its retractive action, (see positions Fig. 7) before the opposite wiper completes its action; thereby causing the second end of the label to be lapped over and'laid u .on the first laid end of the label, by the consecutive undertucking movements of the respective Wipers. Also, enabling the extremities of the wiper-face members 5 to be projected laterally beyond the central axial plane Q, of the bottle neck as illustrated in Fig. 8,'for firmly wiping on the extreme over-lapping outer end of the label.

In Fig. 9 I have illustrated a modification wherein the movable wiper-head is made as a laterally shiftable slide 10 working in guides on the bracket C instead of a pivoted or swinging construction. The actuating lever 20 is also shown as made with a spring-arm 30, engaging with lugs or pins 31 fixed on the slide, for moving the wiper devices toward the central plane. The yieldable wiper-face members 5, their pivot-axis 6 and springs 13 are arranged for operation substantially as first above-described.

In F 10 there is illustrated a modification in which a roller 55 is employed as a wiping-face member; the wiper-head being shown as a slide 10*, and the actuating'lever 30 arranged similar to Fig. 9. a

In Fig. 11 there is shown a modification in which the wiping-face member isconstructed as a pad or tongue 50 of rubber or similar semi-flexible substance; the wiper-head being made as a slide 10 with a socket or'flange for supporting the pad. In this construction the flexible end of the tongue 50 wipes beneath the under curve of the bottleneck as the slide is projected forward by the action of the lever 20 and cam 23 as above noted. A spring 35 is arranged for'retracting the slide 10.

By combining with a setof body-label wipers H rigidly fixed to the wiper-carrier arms, a set of neck-label wipers arranged upon and laterally movable in connection with said arms, the mechanism is rendered capable of the simultaneous aflixment of dual labels, and the handling of neck labels of various styles and degrees of extension, and at the same time performing the wiping operations in a highly efficient manner.
